Reuniting with Sherlock director Paul McGuigan, Andrew Scott has been confirmed as the latest addition to an upcoming adaptation of Mary Shelley‘s Frankenstein.

Known best for his role as Moriarty in Sherlock, Scott is currently acting in BBC Cold War spy thriller Legacy, and is rumoured to be returning for Sherlock’s third series in January. In McGuigan’s Frankenstein movie, he will join major movie actors James McAvoy and Daniel Radcliffe, as well as Downton Abbey‘s Jessica Brown Findlay.

The film, which began shooting in the UK earlier this week, is written by Max Landis (Chronicle), and is set to be released late next year. Little is so far known about its plot, though according to the Radio Times, “Mary Shelley’s gothic classic will be given a twist, told through the eyes of his shuffling helper, Igor (played by Radcliffe).” Meanwhile McAvoy will star in the title role as Victor von Frankenstein, and Jessica Brown Findlay will play a trapeze artist, saved by Frankenstein after an accident.

In an interview with IGN in October, McAvoy said that the film “isn’t based on Mary Shelly’s Frankenstein that much”, though it takes the text as “inspiration”. He went on:

“It’s more of an adventure and the relationship between these two guys – this brotherly relationship that we explore. It’s a really dark adventure – it’s not really an action movie but it’s got a lot of action in it. But it’s really about this relationship that forms the backbone of this adventure that they go on.”
